Clie/Palm screen... streaks?

Some time ago I noticed my Clie had some annoying diagonal streaks on the screen. The person who sold it to me insists he didn't have the problem, and I don't think I recall seeing them until I'd owned it for some weeks. It doesn't impair the operation of the PDA, and I mostly read eBooks, but I'd still like to know what causes it and if there's a fix. Some Googling around hasn't shown anyone else with quite the same problem, so I thought someone from the extraordinary AF community might have an idea

Attached is a photo and a scan of the screen. The contrast has been turned up to make it more obvious, but the pattern remains the same regardless of contrast setting, backlight on/off etc...

You can also try the no-streak hack for the hack manager your using to run afterburner. Ive had more sucess with that...i'll try to find it for you as I dont think its published any longer.

With afterburner, make sure 0-ws core, fast mpx, and fast page is on at least as this gives an excellent speed bump for free without overclocking the processor. These functions just patch bugs in the palm OS. You will notice a large speed bump in any benchmark program.
